This invention relates to a window of the easement type, and moreparticularly, 1t relates to a metal easement window.

The principal object of the invention is the provision of improvedfeatures of construction in a Casement window, for the purpose ofexcluding the elements of weather and particularly to prevent water frombeating its way to the inside, and also to prevent lO seepage frompassing to the inside of the window. y

Another object of the invention is the provision of a cooperative windowsash and frame construction of improved and novel form which weathersthe window at the sill.

Another object of the invention is the provision of a metal easementwindow frame which presents a sill and also a novel ar- Z9 rangement ofstops or abutments, and corresponding stops or abutments on a metalCasement window sash for the purpose of weatherproofing the window.

The nature of the invention and its disr tinguishing features andadvantages will appear when the following specication is read inconnection with the accompanying drawings, in which- Figure 1, is afront elevation of a casement window embodying the invention.

Fig. 2, is a horizontal sectional view of the window.

Fig. 3, is an enlarged vertical sectional view taken on the line 3 3,ofFig. 1.

In carrying out the invention according to the illustrated example, aCasement window frame 10 of metal is adapted to be fixed to a wall ormasonry, and a sash 11, which in the present instance is hung orhingedly mounted as indicated at 12 for swinging movement into and outof the opening presented by the frame 10.

The novel and improved features constituting the present invention willnow be described. The bottom bar 13 of the frame 10 is formed to providean integral sill 14, channels 15, 16 and 17, and stops or abutments 18,19, 20 and 21. It will be apparent that the faces of the stops orabutments are arranged in staggered relationship, parallel to 'eachother, and disposed in the plane of the frame 1.0. Weep holes 22 areprovided in the channels 15 and 16 for a purpose to appear. It will beapparent that vthe sill 14 is of a form to present an ornamentaldependingflange 23 on the outside contiguous the wall indicated at 24,and a depending lnge 25 contiguous the inside of the wall The sash framehas a bottom bar 26 provided with an integral seepage stop 27 whichextends laterally outward and also curved downwardly. A retaining strip28 is attached to the bar 26 and cooperates with an abutment 29 on thestop 27 for the purpose of engaging the lower edge of the glass panel,indicated at 30. The bar 26 is substantially L-shape in cross section,and is provided with stops or abutments 31, 32, 33 and 34. The stops orabutments 31, 32, 33 and 34 correspond to the stops or abutments 18, 19,2O and 21 on the bottom bar 13`of the frame 10. It will therefore beunderstood that the faces of the stops or abutments 31, 32, 33 and 34will be arranged in staggered relationship, parallel to each other, anddisposed in the plane of the sash frame 11. It will now be apparent thatwhen the sash 11 is swung to the closed position, the stops or abutments31, 32, 33 and 34 respectively will Contact with the stops or abutments18, 19, 2O and 21. ln this connection it will be also apparent that thechannels 15 and 17 kallow the stops or abutments 31 and 33 to have thenecessary clearance. The provision of the stops or abutments is such asto present a number of break joints, consequently the weather is keptfrom beating its way to the inside of the window. In ,this way thewindow is weathered. The stop 27 serves Vfor the purpose of deflectingrain beating against the sash 11. It will also be apparent that anypossible water entering the channel 15 will be allowed to run outthrough the weep holes 22. e

It is to be understood that the number and arrangement of stops orabutments, both on the frame 10 and sash 11 may be varied, and that thebottom bar construction of the frame 10 may be of integral constructionor of two or more interfitting parts.

I claim: In a Casement window, a frame compris- 5 ing` a bottom barhaving` a plurality of upstanding` portions defining inner, outer andintermediate walls, a return portion on the intermediate wallterminating Ain a stop, a sash movable in respect to the frame having aplurality of abutments to respectively' engage a portion of the outerWall, the-stop and a portion of the inner wall, and having anotherabutment .extending to a poi-'nt of engagement with the intermediatewall, and a channei connecting the intermediatemand outer wallsreceiving the thrust of said other abutment and bracing theY outer andintermediate walls.
